NeoBurr® FG 169 Plain Tapered Fissure Operative Carbide Bur by Microcopy (USA). Engineered from a single piece of solid tungsten carbide with a standard friction grip shank and a 3.4 mm tapered fissure cutting head featuring a 6-blade configuration. Specifically designed for precise cavity preparation requiring divergent or converging axial walls, defining crisp line angles, creating undercut-free margins for inlays and onlays, and establishing smooth cavity finish lines.

Key Features:

• Precision Tapered Geometry: Tapered profile creates uniform divergent axial walls without undercuts, providing ideal preparation paths of insertion for indirect inlays, onlays, and conservative composite restorations.
• Ultra-Smooth 6-Blade Cutting: Plain (non-crosscut) 6-blade configuration produces a glass-smooth surface finish on axial and gingival margins, minimizing hand finishing and improving restorative fit.
• Conservative 0.9 mm Diameter: Provides optimal access and controlled cutting in tight interproximal areas while preserving healthy sound tooth structure.
• Single-Piece Solid Carbide Construction: Integrated blended-neck architecture eliminates brazed joints, maximizing shear strength and virtually eliminating head breakage under high-speed lateral loads.
• Efficient Debris Evacuation: Continuous flute spacing channels debris away swiftly, preventing clogged blades and minimizing thermal friction against vital dentin.
• Sterile Single-Patient Safety: Individually blister-packaged and pre-sterilized to prevent cross-contamination and guarantee razor-sharp cutting performance straight from the package.
• True Concentric Rotation: Precision Swiss-machined shank ensures true concentricity, protecting turbine chucks and handpiece bearings from premature wear.
